This is a vintage inner box and mechanism for a Gamewell fire alarm Excelsior alarm box. The shell has been sandblasted and repainted and many of the brass pieces have been polished. It is missing the non-interfering coil assembly, terminal , and bell but it does have a code whee l of 23 and does activate and goes through the cycle. The box is 9 3/4" high, 6 3/8" wide and 2 3/4" deep. The lock works great but I do not have an extra key for it. Email if you have any questions. Winning bid pays shipping and insurance.
